Simply put; The best book available to use and self-teach yourself this critical (but sadly dying) art and science.
Bennett's easy to understand technical explanations and simplified reduction tables erases tedious calculations and inherently cancels out errors.
Along with a good sextant, I consider this book a "must-have" item on-board in blue water as well as coastal cruising, 1) as a lifesaving back-up to electronic navigation, and , 2) as a keen mental exercise which links present to past, combining both fun and discipline while increasing your situational awareness.
As an ebook this is about as useful as an ashtray on a motorbike for anyone wanting to use it on a yacht at sea.
